So fairly recently i've been getting a whole host of Blue Screens (see below). These started occuring around a month ago and have been building up in frequency since then. The most common ones seem to happen regardless of what i am using the system for at the time. These are the blue screens i've had. NTFS.sys (Had this once) PAGE_FAULT_IN_NON_PAGED_AREA (Have this regularly) IRQL_NOT_LESS_OR_EQUAL (Have this regularly) DRIVER_IRQL_NOT_LESS_OR_EQUAL (Had this once) SYSTEM_SERVICE_EXCEPTION (Had this once) dxgmms1.sys (Had this once) This system itself is running a Windows 7 RC Build 7100 OS. It has 8gb of DDR2 RAM at 1066 MHz and and AMD Athlon 64 X2 3 GHz Processor. It was installed in June and now has a fair amount of programs on, although it's mostly used for the internet, watching films and occasionally playing games on. I've run a virus/spyware scan to with no results. I've also ran memtest for 48 passes with no errors. I've tried different memory configurations with the same problems and i've also ran several HDD tests with no errors appearing. The minidumps should be attatched however they might be of the bottom two errors. Any help would be much obliged.
